Abstract

The invention discloses a dye monomer and a preparation method and application thereof, and chromatic polymer emulsion and a preparation method and application thereof. The dye monomer is prepared through reaction of reactive dyes and double-bond functionalized reagent, and contains chromophore groups and unsaturated double bonds. Aqueous polymer emulsion with various chromatics is prepared through free-radical emulsion copolymerization of the dye monomer and other monomers. The prepared aqueous polymer emulsion can be used for producing chromatic aqueous polymer products directly without adding additional dyes or pigments, and has wide application prospect in the fields of aqueous ink, aqueous paint, aqueous coating, leather and fabric finishing agent and the like.

Description

technical field [0001] The invention belongs to the technical field of materials and fine chemicals, and in particular relates to a dye monomer and a colored polymer emulsion as well as their preparation method and application. Background technique [0002] As the basic raw material for the preparation of water-based polymer products, water-based polymer emulsions have been increasingly used in people's production and life, including well-known daily chemicals such as wood paints and adhesives, as well as architectural coatings. , Metal anticorrosion and other industrial coating supplies. Since water-based polymer products use water as the medium, it not only saves a lot of organic solvents, greatly reduces or even eliminates the harm to the environment, but also significantly reduces product costs, so it is more and more used in construction, industrial coating, papermaking, etc. , leather, printing and dyeing and other fields. [0003] At present, various colorful water-...
